What is a builder's level used for in excavation projects?

A builder's level serves a critical purpose in excavation projects, primarily utilized for setting cut stakes accurately. It is designed to establish a horizontal line of sight for the operator, allowing for precise alignment and elevation control when determining where the earth needs to be excavated or filled. When a builder's level is used, the user can ensure that the stakes are placed at the correct height relative to the desired grade. This is crucial for maintaining the proper slope and ensuring the stability of structures to be built on the excavated land.

In the context of excavation, having properly set cut stakes means that excavation equipment and labor can work more efficiently and accurately, preventing over-excavation or under-excavation. This helps in reducing material costs and ensures that the site is prepared correctly for the upcoming construction phases.
